Säcken Reef, to be precise.  That’s Sweden’s one remaining coral reef, dominated by this cold water Lophelia pertusa which lives without the help of zoothanthellae by capturing food that has fallen onto it from above.  These corals inhabit an extremely cold and deep region of the ocean off the coast of Sweden, and there is concern that ocean trawling will destroy this last remaining reef builder in the far Northern region.  The larvae of this coral probably ended up there from currents coming down from Norway, and as the reef gets smaller and smaller efforts are being made to bring more larvae down to populate this area.  More info HERE.
